Sometimes get a rough idle and misfire after about 2 miles, bad enough that the CE light blinks.

almost always happens when there is a big change and temperature from warm to cold, like 70 degree days to 30's to 40's at night. Once I pulled over, turned it off, the restarted and it didn't return that day. Never happens with the opposite temp swing, that is the morning that it...

I plan to swap the 04's engine into the 02. I'm wondering if there are any changes that need to be made (sensor swaps, etc) or should it be plug-n-play? A close inspection shows them to look identical, but I'm wondering if any of the electricals need to be changed from the '02 onto the '04 block before plugging it in.

I have a 2003 trac with 240,000 miles and job 2 engine. I've had this vehicle for 12 years and it doesn't owe me a dime, virtually trouble free except for the p0171/p0174 issues. The truck still seems to run fine, maybe I've been driving it so long i just can't tell.

Anyway, I've been chasing the p0171/p0174 issue for years and haven't been able to figure it out, despite all of the great info on this forum, but maybe I just found something.

Battery seems to have enough juice. Radio works. A/C works. Everything sounds and looks normal until I turn the key. Then all I get is a lot of stuttering lights on the dash and a ticking/clicking sound.

FML. Any idea what this could be? It was working fine this morning when I drove it to work. Starter?
